Abstract: PROBLEM TO BE SOLVED: To surely extract a contour line at a high speed by an image processing tool for executing image processings like color conversion and a filtering processing and a computer vision for area-dividing images and understanding a scene, etc. SOLUTION: A contour section to be extracted is specified (S1). A start point specified in S1 is turned to the initial position of a point under consideration and also an end point is set as the target point of contour tracking (S2). The position relation of the point under consideration and the target point is calculated (S3) and a hiding mask for hiding pixels near the point under consideration is prepared (S4). The masking processing sets a constraint for being surely converged to the target point while allowing the considerably free tracking of the contour line. The pixel of maximum edge strength is searched from the pixels near the point under consideration (S5) and the searched contour pixel is set as a new point under consideration (S6). S3-S6 are repeated until the new point under consideration matches with the target point (S7).

Title: Rainfall/device fault discrimination system and its device for satellite communication system
Inventor: DOI KEISUKE
IPC: H04B17/318
Filed: 1998-01-21
Abstract: PROBLEM TO BE SOLVED: To clearly discriminate whether a fault in a satellite circuit is caused by rainfall or the fault of a device itself. SOLUTION: This rainfall/device fault discrimination system includes a satellite communication system, where a master station 1 is connected using a TDMA system to plural slave stations 5 via a communication satellite 3. Based on a rainfall attenuation a1 of a prescribed reference wave P sent from the satellite 3 and detected at the station 1, a down rainfall attenuation Md2a of a continuous wave C is calculated against an up rainfall margin Mu2 of a burst wave B by means of a circuit design. At the same time, a value obtained by adding the attenuation Md2a of the wave C to the total rainfall attenuation (U1 -T) of the station 1 to which the transmitting power control value T of the station 1 is added is defined as a threshold T1 of the received level attenuation of the wave C at each station 5. Then it is determined that a fault of a satellite circuit is caused by a rainfall from the fact that the station 1 is unable to receive the wave B from the station 5 after the received level attenuation (x) of the wave C detected at the station 5 exceeds the threshold T1 .

Filed: 1983-01-24
Abstract: PURPOSE:To enable improvement in modulating sensitivity by noticing that the interaction between free electron or hole and light increases with an increase in wavelength and transmitting the light to be modulated through the inside of a semicondcutor sample in a resonator to change the density of the hole. CONSTITUTION:Light Pi to be modulated is made incident through a window having a dielectric multilayered film 5 on the left side and a forward voltage is impressed through an ohmic electrode 4 to the p-n junction between a carrier confinement layer 2 and a high density layer 3. The high density carrier of the layer 3 is injected into the layer 2 and the carrier density in the layer 2 is largely changed, as the effect of said voltage impression. The amplitude and phase of the light Pi are consequently modulated by the change in the carrier density of the layer 2. If the distance between the resonators is adjusted to a prescribed value, the reflected light Pr taken out to the outside near the sharp resonance peak of the resonator is subjected to the much intensified amplitude and phase modulation by the resonance effect. As a result, the modulator for IR light or far IR light having a small size, high efficiency and high speed is realized.
